The New Mexican [EPUB ebook] 

Zepaniah Bierman, a mustanger turned hunter, lies on the top of the rocky sandy arroyo. Sweat trickles down his face and stains the shirt across his back as the sun beats daggers of heat on the Chihuahuan desert. Out there is a scout for three riders that torched his ranch in Mesilla. The only way out of this eternal furnace is back to New Mexico; Zep will track them there encountering Mexican cavalry, Apaches, outlaws, and a strong-willed young woman that wait for him. His trail carries him from Old Mexico to Santa Fe, surviving the Jornada del Muerto, and covering the length of 1858 New Mexico Territory discovering deception, heartbreak, ambush, friendship, love, and a resolution at the end of his odyssey that is terrifying.
